RMC1/10K3400FTP Equivalent & Substitute Parts

Part Overview

The RMC1/10K3400FTP is a 340 Ohm ±1% 1/8W (0.125W) chip resistor manufactured by Kamaya Inc. in 0805 (2012 Metric) package format. This thick film resistor operates across -55°C to 155°C and is supplied in Tape & Reel packaging. The part is currently Active in product status with 871 pieces in stock inventory.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain constraints occur, or when design requirements call for alternative qualified sources with equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/10K3400FTP is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 340 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Mechanical Parameters:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

All five substitute parts listed meet these core substitution criteria. Additional features such as Automotive AEC-Q200 certification or moisture resistance represent enhanced capabilities that do not prevent substitution but indicate suitability for specific application environments.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Highest Availability):

ERJ-6ENF3400V (Panasonic) and RMCF0805FT340R (Stackpole) are recommended as primary substitutes. Both parts are Active in product status with substantial inventory availability (54,595 and 7,343 pieces respectively). Both carry Automotive AEC-Q200 certification, indicating qualification for automotive-grade applications. ERJ-6ENF3400V offers the highest inventory level among substitutes.

Secondary Substitutes (Active Status, Standard Applications):

RC0805FR-07340RL (YAGEO) is Active with 21,268 pieces in stock and includes moisture-resistant thick film composition. KTR10EZPF3400 (Rohm) is Active with 6,705 pieces and includes both Automotive AEC-Q200 and High Voltage features.

Discontinued Part (Not Recommended for New Designs):

MCR10ERTF3400 (Rohm) is listed as Discontinued at DiGi Electronics and should not be selected for new designs or long-term production applications, despite meeting all electrical and mechanical equivalence criteria.

Compliance Considerations:

All Active substitute parts are RoHS3 Compliant and REACH Unaffected, matching the regulatory status of the primary part. MSL rating of 1 (Unlimited) is consistent across all parts, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF3400V replace RMC1/10K3400FTP in any application?

A: ERJ-6ENF3400V meets all electrical and mechanical equivalence criteria: 340 Ohm resistance, ±1% tolerance, 0.125W power rating, 0805 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The maximum seated height differs by 0.05mm (0.70mm vs 0.65mm), which is within typical PCB assembly tolerances. Automotive AEC-Q200 certification on ERJ-6ENF3400V represents an enhanced qualification level suitable for automotive applications.

Q: Why is MCR10ERTF3400 listed if it is discontinued?

A: MCR10ERTF3400 is included in the equivalence reference because it meets all electrical and mechanical substitution criteria and may remain available through secondary distribution channels or existing inventory. However, it should not be selected for new designs or applications requiring long-term supply assurance.

Q: What is the significance of the height difference between substitute parts?

A: Seated height variations (0.60mm to 0.70mm) are within standard PCB assembly specifications for 0805 components. These differences do not affect electrical performance or mechanical compatibility with standard 0805 footprints. Height specifications are provided for applications with strict vertical clearance constraints.

Q: Are all substitute parts RoHS compliant?

A: All Active substitute parts (ERJ-6ENF3400V, KTR10EZPF3400, RC0805FR-07340RL, RMCF0805FT340R) are RoHS3 Compliant. MCR10ERTF3400 is also RoHS3 Compliant but is discontinued.

Q: What does Automotive AEC-Q200 certification indicate?

A: AEC-Q200 is an automotive industry qualification standard for passive components. Parts carrying this certification (ERJ-6ENF3400V, KTR10EZPF3400, RMCF0805FT340R) have undergone additional reliability testing and are approved for automotive applications. This certification does not affect substitution eligibility for non-automotive applications.

Q: Can I use RC0805FR-07340RL in high-temperature applications?

A: RC0805FR-07340RL operates across the same temperature range (-55°C to 155°C) as the primary part and all other substitutes. The moisture-resistant thick film composition is an additional feature that does not alter temperature performance specifications.
